Pine Bind, Aria, assignors to International haper Qumpauy, New York, Nlltl, a corporation of New York li iled .l'uiy 5, 1&2, Ser. No. 287,963 20 (til. I5636I) This invention relates to paper roll finishing. More particularly, it relates to an apparatus made up of several sub-assemblies which cooperate to accomplish the objects of gluing the loose tail of a paper roll to the body thereof and plugging the ends of the hollow cores about which the paper roll is wound for purposes of storage and shipment.

Broadly, the present invention encompasses an electromechanical unit havin rotatable roller means for positioning an unfinished paper roll initially with reference to a gluing sub-assembly which effects the application of paste or glue on the roll or on the inside surface of the tail end of the wound paper web and then with reference to two reciprocatingly movable core plugging sub-assemblies which effect the insertion of plugs made of wood, metal, or plastic into both ends of the hollow core forming the axle of the paper roll to give such core added strength and to provide a mems of purchase on such roll. In addition, the rotatable roller means are adapted to eiiect the pressing of the paper web tail against the body of the rolled paper web when glued and the core plugging subassemblies are adpted to select pairs of plugs from random assortments thereof and, by means of a built-in capacity for self-adjustment, to position such pairs axially of the hollow core. Further, the unit can include means for facilitating and regulation its paper roll intake and discharge.

For a better understanding of the present invention, reference should be had to the attached drawings in which:

FIGURES 12, 13 and l4, l5, and 1-5 show circuit di- 2 grams in accordance with the present invention.

FIGURE 1 depicts the equipment of the present invention from above, including horizontally disposed rollers 1i) and 32.. FIGURE 2 illustrates the positioning of paper rolls with respect to such equipment. Thus, roll A is poised on inclined plane or ramp I3 whe c it is held back by a chock which is connected to and movable with piston 15 when urged by fluid pressures in cylinder 16. Solenoid I7 dictates such pressures. Again, roll B is positioned on rollers It and ill at about floor level, having been halted in its progress out of the situation or" side view of the equip 3,l52,5bh Patented Dec. 22, 1%64 roll A down ramp l3which progress began with the withdrawal of choc; i l from a point where roll B impinged against itby chock 13 connected through rod 19 with fluid cylinder 26 and solenoid 21 therefor. Conveniently, such positioning takes place when roll C (having been finished in accordance with the present invention, kicked off rollers It) and ill by prod roller 22 on forked roller-bearing piston 23 in fluid cylinder 24 operated by solenoid 25 at about the time chock l8 and rod Ii disposed therein are retracted, and rolled by gravity farther down ramp 13 and into trough 26) leaves a gap across which light beam 27 can travel freely (as it could not when roll C lay in such gap) from its source 27a to a detecting means 27b therefor to signal for the forwarding of the next unfinished roll down ramp 13 to rollers 1i? and II. Similarly, it is convenient and preferable to have the action of prod roller 22 on the roll resting on rollers 16 and I1 timed to follow the finishing of such roll in accordance with the invention.

Parts of the gluing sub-assembly and phases of their operation are shown in FIGURES l, 3, 5, and 7. Unfinished roll A, having descended down ramp 13 to rollers It and II, is caused to rotate slowly thereon in clockwise fashion, as viewed in FIGURE 5, in response to a predetermined signal to the drive means 28, e.g., motor, connected to the rollers. Means D and E providing air jets lift the tail F of roll A as it rotates slowly, so as to cause such tail to fall substantially flatly against the downroller end of ramp 13. When tail P so falls, it interrupts light beam 29, emanating, for example, from light source means 29a and impinging on light detecting means 2%, until the continued slow rotation of roll A draws tail F from between 2% and 29b and beam 29 passes between them unimpeded. Once such interruption ends, rollers I9 and II are caused to stop the rotation of roll A by means of a signal transmitted to roller drive means 28 from detecting means 2%.

At this juncture, gluing heads 30 mounted on horizontally disposed pistons Ilia in pneumatic cylinders 31, which are, in turn, mounted upon the divergently and convergently movable core plugging sub-assemblies, should be considered. Pistons 332a are adapted to move, in response to a predetermined signal, along their axes and relatively to such sub-assemblies and to carry gluing heads 59 toward or away from each other. The set of the heads 39 is preferably such that the sprays emanating from them, when the cylinders approach one another, for example, above the upper surface of tail F or roll A, cross to give the most efficient gluing pattern thereon. To prevent rotation of heads 3% and pistons 31a within cylinders 31 and the loss of their setting, pilots 32 are fastened at their upper ends to the pistons or heads and slida-bly engaged at their lower ends in charnel 33 (FIGURE 7). Cylinders 31 do not, however, feed gluing heads 30; this is done by means of glue hoses 34 which are in a fluid connection with heads 34?.

Gluing heads 3d and pilots 32 are also so positioned in relation to one another that, preferably, at least one of them can by means of feeler 35 actuate a switch 36 when the gap between them decreases to a certain predetermined minimum length. The actuation of switch 36 results both in the ending of the strokes of pistons 31a toward one another and in the ending of the glue flow from heads 3'0 mounted on such pistons. Preferably, it also results in the mutual retraction of pistons 31a and in the re-energizing of drive means 23 for the purpose of rotating roll A on rollers ltland ill to permit the drawing-up of tail F between the body of roll A and the upper surfaces of rollers It and II and the affixing of glued tail F to such body with the aid of the weight thereof.

Where the core plugging sub-assemblies do not participate in the roll tail gluing operation, they cooperate therewith. Such sub-assemblies include plug hoppers 49 which are depicted in FIGURES l, 3, 4, 6, l0, and 11. These plug hoppers include truncated hollow core barrels 40a, into the open narrow end of which the plugs 40!), which can be hollow, are initially dumped at random. Barrels 40a are rotated about their laterally disposed longitudinal axes by drive means ttic as soon as the equipment is initially turned on or even before the gluing operation begins and plugs 4% are thereby caused to move down the sloping interiors of barrels 49a toward barrel backing plates dild and into plug orienting apertures 406 formed by means of and between barrels 40a and plates 4tld. A complete movement of plugs dill) into apertures 40:: is, preferably, made to depend upon a juxtapositioning of plugs 40b such that their profiles generally and perhaps somewhat loosely conform to the predetermined configurations or outlines of the apertures.

Funnel members 4% are a part of plug hoppers 40 and of the core plugging sub-assemblies oi the present invention and they are provided to keep plugs 40b, once oriented for further use by means of apertures see, from falling through such apertures, from becoming disoriented, and in a systematic flow to the rest of the core plugging sub-assemblies. Such funnel members are themselves adapted to serve several functions. By means of the downwardly depending throats or necks lt g of such members, the oriented plugs dill: leave apertures iile of barrels 40a when the revolving barrels and apertures bring them into registry with mouths 40h at the upper ends of necks 4g and are directed toward plug pick-up stations 39 at the lower ends of necks 40g. By means of cheek pockets 4th of such funnel members, a few overflow plugs 4% which cannot find space in necks 40g are kept temporarily stored and oriented until plug removals at stations ltlj permit them to enter into necks 449g. Larger overflows are, of course, returned to barrels 4% from pockets dtli for further agitation and eventual reorientation.

I With the disposition of a pair of oriented plugs at pickup stations 40 it is timely to consider the elements of the core plugging sub-assemblies of the present invention other than plug hoppers 40. Most of such elements are combined to provide two devices which cooperate to efiect the same principal purpose, i.e., the plug of the hollow paper roll cores, but which are capable of a certain degree of independent action or adustment in achieving such results. These devices include reciprocating trolley car riage members 5th and 7t? movably mounted on pairs of horizontally positioned trolley lead screws 51 and 71, respectively, by means of pairs of trolley sleeve nuts 52 and 72, respectively. Lead screws 51 and 711, which lie parallel to rollers 10 and ill, but preferably below floor level, are connected for rotation to respective reversible drive means 53 and '73, which are disposed beneath such screws. When rotated by such drive means, lead screws 51 and 71 can carry trolley carriage members 5% and 70 away from each other, at least until some portions of such members impinge against shut-off switch means 54 and 74 connected to such drive means. means 54 and 74am positioned to provide the shut-oft at such times as trolley carriage members 50 and 74} are suitably disposed before oriented plug pick-up stations 7 As shown in FIGURES 4, Sfand 9, fluid cylinders 55 and 75, which are mounted horizontally on elevator plates Shut-off switch and 80 are disposed within frames 59 and 79. It will be noted that frames 59 and 79 and cylinders 6t} and 8t) lie between horizontally positioned and substantially triangular, spaced pairs of elevator plates 569a and Stlb and 7M and 76b within trolley carriage members 5% and '70 and that such elevator plates form, together with elevator spacer sleeve nuts 61 and 81 mounted on vertically disposed, rotatable elevator lead screws 62 and 82, elevator carriage members 63 and 83. Elevator plates 59a and 50b and 7% and 702; are maintained in a parallel relation by nuts 61 and 81 to the ends of which such plates are aflixed by welding or the like.

When pistons 56 and 76 are ejected, in response to a predetermined signal, from cylinders and '75, they cause, with the aid of the noted linkage, cylinders 6i) and St? to revolve approximately 90 from positions within elevator carriage members 63 and 83 and paralleling rollers 16 and ill to positions substantially without members 63 and 83 and axially or oriented plugs dill) in pickup stations at And, when 6% and 89a are ejected, in response to another predetermined signal, from cylinders 6t? and 80, their outer ends-which can be adapted to impale or grasp the plugs, preferably looselypick up the plugs. Thereafter, spindles 6th: and Sila and pistons 56 and 76 are or can be retracted into their respective cylinders, cylinders 6b and till are or can be returned to positions parallel to rollers ill and 11 as shown in FIG- URES 3, 6, and 7, and trolley carriage members 59 and 70 are or can he traveled toward one another and toward paper roll A on rollers ill and ill by the actuation of lead screws 51 and 71 and their drive means 53 and 73.

Trolley carriage members 50 and it? are not required to arrive simultaneously at the ends of roll A. Such a simultaneous arrival can, as a matter of fact, occur only if and when roll A is initially positioned with a degree of accuracy which takes into minute account the speed and distances members 59 and '70 travel. But, when they do arrive, as shown in FIGURES 1, 3, 6, and 7, electrical switch means 64 and 84 mounted on the forward ends of members 5% and 7d are brought into play in like fashion; namely, such switch means, having made contact with a roll end, stop the forward progress of the trolley carriage member to which they are aflixed. Then, when both switches 64 and 84 have stopped the flow of energy to drive means 53 and 73 of lead screws 51 and 71 and the forward progress of trolley carriage members 50 and 70 as shown in FIGURE 9, energy is caused to flow to drive means 65 and 85 for lead screws 62 and 82 on which elevator carriage members 63 and 83 are mounted. Drive means 65 and-85 and lead screws 62 and 82 are respectively connected by means of stand ard worm and bevel gear arrangements 66 and 86. With 1 the energizing of-drive means 65 and 85, lead screws 62 and 82 turn and, at, preferably the same rate of speed, cause elevator carriage members 63 and 83 to rise within stopped trolley carriage members 5% and 7d. 7

7 As shown in FIGURES 7 and 9, a light source means 67a is mounted on elevator plate 50a in the vertical 50c; and 70a in trolley carriage members Sti and'7tl by means of clevises55a. and a, hold ends of pistons 56 and 76, the other ends of which are pivotally attached through horizontally rotatable lever arms 57 and 77 to vertically disposed rotatable shafts 58 and 78. As also shown, frames5 and '79 are aflixed on their endplates plane of spindle etla and plug 40g impaled thereon. By

design, such vertical plane bisects the horizontal distance between the centerlines of rollers 19 and 11. Further,

light source means 67a is directed to cast a beam of light elevator plates 5llaas soon as the'rise of elevator car-= Iiage members 63 and 83 Within stopped trolley carriage members 59 and 74 brings means 67a and 67b to or near the lowermost edges of the open ends of core G.- 1 .Themoment beam 67 is sighted by detecting means.

6712, a timer means is actuated; thereby and it regulates the further upward movement of elevator carriage members 63 and S3 to the extent that they will rise no further than the vertical distance between the axial lines of beam 67 and spindles 60a and 80a and to the extent that they will locate plugs 46b impaled on such spindles axially of hollow core G.

Plugs see are inserted into the ends of core G by means of the extension of spindles 60a and 89a out of cylinders 64 and 89 in repsonse to a predetermined signal which is, preferably, initiated by the timer means. Plugs 435 are then driven home in the ends of core G with the help of flanged collars 6th) and 89b on and affixed to spindles 60a and Ella, respectively.

It is upon the withdrawal of spindles 60a and Sill: from core-inserted plugs 40!; that, preferably, the roll tail gluing operation enters the gluing head retraction phase. Or, in other words, the preferred sequence cornprehended by the operation of the present gluing subassembly and core plugging sub-assemblies sees tail F of roll A blown to lie fiat down ramp 13 not later than the pick-up of oriented plugs dill; at stations 4tlj and sees tail F glued when trolley carriage members 50 and 70 have brought impaled plugs 49b to the ends of roll A. This will be better understood from a review of the circuitry for the present equipment shown in FIGURES 12 to 16.

Assuming that the machine of the present invention is empty and that the roll to be finished (roll A) is still on ramp 13 held by chock 1d, the preferred mode of operation and the means of effecting it are as follows:

Referring first to FIGURE 13, the poweron button is pushed to energize relay coil R1 and, thereby, to close contacts Ric, Rib, and Ric. Power is now supplied to the machine and, in particular, to light 27a. Light 2% casts a beam 27 of light toward photoelectric cell 2712 which reacts by closing contact 270 and transmitting electrical current to relay coil R3. When thus energized, relay coil R3 causes contact R311 to close. This permit relay coil R2 to be energized through now closed contact Rita and normally closed contact TRia when the machine operator presses push button P231 to begin the machine sequence.

Energized relay coil R2 causes the closing of normally open contacts RZa, R212, and RZc; permits the release of P31, by the operator; and, provides current through now closed contact R20 and normally closed contact 315a for relay coil R4 which enables the closing of contact to which core plugging sub-assembly hopper drive chic are connected and the energizing of such drive means for the purpose of beginning a sorting of pin gs in barrels lilo.

Once contact R25 is closed, timer relay coil TRl is energized and closes contact TRlb. Solenoids l7 and 21 are also energized; the energy flowing to solenoid 17 operates a valve therein which causes the retraction of piston 15 into cylinder 16 and the removal of chock i l from in fron of roll A and that flowing to solenoid 21 operates a valve therein which causes the extension of chock 1 5 on piston 19 from cylinder 21? into the path of roll A upon its release by chock 1d. The energy in relay coil TR etiects the starting or" the timer which is connected thereto and is adapted to open normally closed contact TRla, thereby de-energizing relay coil R2 and opening contacts 32a, R21), and R20, but not contact Rda, when a predetermined amount of time has elapsed and allowed roll A to move down ramp l3 and to settle upon and between rollers it) and ii, perhaps with the aid of chock 13 on extended piston 19. And, at about the same time, the coming-to-rest of roll A on rollers it and i interrupts light beam 27, causing contact 27c to open, relay coil R3 to be (lo-energized, and contact R3a to open, so that even an accidental pushing of P131 by the operator will not cause another unfinished paper roll to come down ram; 13 into collision with roll A.

When contact TRIrb is closed en rgy can flow to the latching means of latch relay LRl, can close contact LRla, and cm energize relay coil R5. The energizing of relay coil R5, which is connected to drive means 28 for rollers 18 and 11, starts such drive means and causes rollers ill and 11 and Roll A thereon to rotate. it also contact R551 so as to energize spring-loaded solenoid valve 99 (FIGURE 12), which is in iiuid connection with air pipes or hoses designated as arrows D and E in FIG- URE 5 and to cause air jets emanating therefrom to blow tail F of roll A into the beam 29 of light 2%. The interruption of the transmission of beam 29 to photoelectric cell 29!) closes contact 29c and energizes relay coil R6. When relay coil Rd is energized normally open contacts R611, R61) R60 are closed.

The closing of contact Rea causes current to flow to the unlatching means of latch relay LR}; the closing of contact Rob assures a continued tlow of current to drive means 28 at least until tail F no longer interrupts beam 2? and, as a result, contact 290 opens and effects the tie-energizing of relay coils and R6 and the solenoid having valve 99; and, the closing of contact Rec causes current to ilow to the latching means of latch relay LRZ which is electrically connected to drive means 53 and 73 for lead screws 51 and it.

When latch relay LRZ is thus energized, contact LRZa closes, energizing relay coils R7 and Re through normally losed contac s 6 m and 84a of limit switches 64 and Relay coils R7 and RS energize drive means 53 and i3 causing trolley carriage members 5% and '73 to approach opposite ends of roll A until physical conatct is between such limit swtiches and such ends, and the switches are thereby opened.

When limit switch contacts 6% and t de: are opened, contacts 6% and 34b are closed, so that current flows to relay coil R? through normally closed contact Lima. Energized relay coil R? closes conacts R9: and Pe /b and causes current to liow to the unlatch-means or" latch relay 1R2 (whereupon relay coils R7 and R8 are deenergized to stop drive means 53 and 73) and to drive means 6d and 85 (whereupon elevator carriage members 63 and 83 within trolley carriage members St? and it? start to rise on lead screws 62 and 82 connected to such drive means) During the ascent of elevator carriage members as and 83, light tila casts a beam s7 through hollow core G of roll A to impinge against photoelectric cell 5722, as soon as there is a clear path, and to cause the closing of contact 67c. When contact 67s is closed, the latching means of latch relay LR?) is energized and closes Contact 112%. Now, both contacts 11% and Lilia! are closed, permitting the how or" current to the starting means or a timer TRZ which is set to end the ascent of elevator carriage members 63 and 33 when they have travelled the predetermined vertical [ilSLtlElCfi between the line of beam 67 and the center-lines of spindles impaling plugs ltib within members 63 and it such point, plugs 4% are positioned substantially axially of core G or" roll A and timer TRZ closes contact TRZEa, so as to energize the latching means f latch relay and open normally closed contact LRa, which opening shuts oii drive means 65 and 85.

Further, energized latch relay Lilo closes normally open contact LR ic, thereby energizing spring-loaded solenoid valves 91 and 92 which are connected to cylinders 6t? and till and solenoid valves 93 and $4 which are connected to cylinders 31 and, by hose line 34a, to glue heads Thereupon cylinders and eject spindles 6th; and Silo bearing impaled plugs 4%)!) into the ends of core G of roll A and cylinders 33 eject pistons 31a bearing glue heads 3% while solenoid valves 93 and 5% supply air to glue heads 38. Latch relay LR l flso closes normally open contact LR-db, thereby energizing timer relay TR3 which is adapted to open contact TR3a, ole-energized solenoid valves @land 92 at the end of a predetermined period marked by withdrawal of spindles diia and from core-lodged plugs 49b, and close contact TR3Z). On the other hand, solenoid valves 93 and 94 are de-energized when feeler 35 strikes switch 36.

When contact TR3b closes, relay coils R10 and R11 are energized and, through them, drive means 53 and 73 for lead screws 51 and 71. Relay coils R10 and R11 are subsqeuntly de-energized when trolley carriage membens d and 7% move apart sufiiciently to impinge at their rear ends against limit switch contacts 54a and 74a. When this occurs, limit switch contacts 5% and 74b are closed and relay coils R12 and R13 are fed current. With the flow of current through relays R12 and R13, reversible elevator carriage member drive means 65 and 85 are started and carriage members 63 and 83 begin to descend.

Contact R125 is, in turn, closed and allows current to i flow to the valve of solenoid which causes the ejection of piston 23 from cylinder 24 and, thereby, the nudging of roll A off of rollers 16 and 11 by prod roller 22. Such descent is ended when carriage members 63 and 83 come down on and open normally closed limit switch contacts 6% and 59a to de-energize relays R12 and R13. W'hen limit switch contacts 6% and 5% are opened, limit switch contacts 591) and 8% are closed and this makes current fiow to relay R14 and timer TR i.

Energy in relay R14 closes contact 1114c: and energizes solenoid valves 95 and 96 connected to cylinders 55 and '75. Energized solenoid valves 95 and 95 cause the ejection of pistons 56 and 76 from cylinders 55 and 75 and, by means of levers 57 and 77 and pivot shafts 58 and 78, the swinging of cylinders 60 and 34 through arcs of about 96 to positions axially of oriented plugs in hopper pick-up stations The swinging of cylinders 65 and 85 through arcs of about 90 causes them or spindles 681a and 85a to impinge against limit switches 68 (FIGURE 8) and 88 (in like positions on elevator carriage member 33). Such limit switches are thereby closed, so as to energize relay coil R15 and open normally closed contact Rlea. The opening of such contact stops hopper drive means 460 connected thereto. Energy in relay R15 also energizes solenoid valves 91 and 92 to extend spindles 69a ad Slia from cylinders 69 and 89, so as to impale oriented plugs 40b in pick-up stations 45 At this juncture, energized timer TR4 is adapted to open normally closed contacts TRda and TR- lb, thereby tie-energizing relays R14 and R15. When relay R15 is de-energized, spindles titia and 86a retreat into cylinders 55 and 84?, taking along impaled plugs 4012. When relay R14 is de-energized, cylinders 65 and 80 swing back through arcs of about 90 to positions generally parallelling rollers in and ill, because of the retraction of pistons 55 and '75 into cylinders 55 and 75. a
